I would try contacting google first for your options, if nothing hits your fancy there, either buy a new chromecast or open it up and re-paste, note that if it has been on contact with liquid, even near steam, water will have ingressed inside and that's the cause of the overheating. something shorting (even a little) inside on that board will cause havoc and overheating.

I have this issue right now on my A1342 13" 2010 MacBook. You can open her up and theres screws on the trackpad that you can turn to tighten or loosen up the trackpad. Trial and error is involved. I can only click on the left side of my trackpad, but the right side is super sensitive. Light pressure registers a click. I came home and when I went to use it the issue was there. Weird, a few hours ago it didn't have this issue. maybe someone stood on my computer as I left it open and on the floor! Well, at least it wasn't the screen! Ahh, the joys of living with a family...

The mistake you made was plugging it in, and leaving it in the water for ten minutes. The corrosion on the board is probably too great for it to be repaired (unless you go professional, but I can't guarantee that it will work). The phone is pretty much a brick now. My suggestion would be to go buy yourself a newer iPhone or a phone of similar or better spec.

you need to tighten them. It's a pretty universal process. It can be fairly fiddly, having another person help you tighten it whilst you hold the pads just above the wire. another guess at this is that you may need new brake pads, they are consumable and can wear down. tightening them works until you need to buy new ones, it's basically re-calibrating them. The closer to the wheel they are, the more likely they are to stop it, so I recommend you look up a guide on google "How to tighten bicycle brakes" or how to calibrate them. I'm not a mechanic, but I have experienced this issue with my bicycle!

connect an ethernet cable (if possible) and hold down the option key and r at the same time- if it doesn't work, Apple geniuses can help. the option key on it's own brings up bootable storage devices connected to your mac - try that and see if anything comes up, it allows you to set up wi-fi with the efi firmware, too.

replace LCD, it is malfunctioning. LCD's are more fragile than you think- they can crack if you put pressure on the back of the notebook, or maybe you accidentally closed it with something in it. Before buying an LCD, make sure the pins on your LVDS connector on your mainboard aren't bent or deformed, as this may cause issues with displaying stuff. if all is clear, get the correct size LCD for your notebook. LCD replacements are easy! I wish you good luck with resolving your issue, and if you are in doubt when purchasing your replacement LCD, I am here. If you don't feel up to it, Your local repair shop is waiting for you- they may even help you more than me with the part! just ask them if they can help you get a spare LCD for your laptop - they may let you buy it from them! weeowey

since you're replacing the phone's memory components, which in turn hold the data about whether it's locked or not, then I guess it would work. you would have to write down the new serial number and IMEI, too of course. make sure to get an american logic board that is unlocked tho. you're better off selling that phone on eBay as "New" and buying an unlocked american one. this will allow you to bypass annoying EU volume restrictions, therefore making the internal speaker louder ;) I own one and it seems louder. probably just an illusion tho

I would also suggest reporting bad websites to apple's bug reporter that take a malicious advantage of security flaws in Safari. totally worth it; reporting the sites allows them to fix these holes, you see ;)

Use a longer, sturdier screw driver. Either that or the screws have been thread locked in too tight at the factory. Apply more pressure. I mean, way more like, medium-hard pressure. if you don't care that much, apply hard pressure (If you're desperate apply even harder, just not so much it cracks the glass). Pressure is what holds the screwdriver in the screw, prevents it from slipping and stripping the screw! This is probably bad advice... I know.
